Specification of Letters Patent. Patented Dec. 26, 1916.

Application filed March 25, 1915. 'Serial No. 16,845.

yfireplaces for heating rooms of a building and the object of my improvement is to provide a fireplace which shall embody a chamber having an inlet passageway for admitting fresh air thereinto and' having outlet openings or passageways communicating with the room or rooms to be heated whereby the fresh air that enters ysuch chamber through said inlet passageway maybe heated and thereupon flow out of said outlet passa geways into such room or rooms, the walls of said chamber and a portion of the walls of said inlet passageway being disposed to be subjected to direct contact with a fire burning within such replace, thus to eect great economy in the consumption of fuel.

I accomplish this object by devices illustrated in the accompanying drawings where- 1n- Figure 1 is a perspective view of a fireplace embodying my invention; Fig. 2 is a view of the same in vertical mid-section on broken line :c of Fig. 3; and Fig. 3 is a view of the same in horizontal section on broken line y, y of Fig. 2.

Referring to the drawings, throughout which like reference numerals indicate like parts, a re receptacle, preferably of cast iron, comprising a bed-plate 5, vertical end` walls 6, an upwardly and outwardly curved back wall 7, and a smoke flue 8,r is disposed within a rectangular brick inclosure 9 which is provided with an opening 10 in its front wall, which opening 10 registers with the open front side of said fire receptacle'y and which is disposed against a wall of a room in connection with a chimney 11.

The smoke flue 8 is disposed at an angle that adapts it to extend from the front portion of the top ofsaid fire receptacle to the chimney 11 through a chamber 12 formed by the brick inclosure 9, and extending vertically upward through the bed-plate 5, and through the curved back wall 7 is an air flue 18 through which fresh air may pass from a brick-inelosed air flue M into the chamber 12, the brick-inclosed air flue 14 being provided with an inlet opening, not shown,

through which'fresh air may be admittedtliereinto, as more clearly shown in Fig. 2.

The flue 13, in horizontal cross-section, is oblong in form whereby its front wall may present a large area to a direct contact with a fire burning within said iire receptacle thus to'impart heat to the fresh air that may iow upwardly therethrough and the curved back u all 7 serves as a portion of the front wall of the chamber 12 whereby fresh air within such` chamber 12 may be"quickly Yheated by 'heat conducted through such vcurved back wall?v which is directly eX- posed to the fire within said fire receptacle. Disposed on the bed-plate 5 is a lire grate 15 upon which fuel may be placed to burn.

- Extending through the bed-plate 5 fromthe air-flue 111 to the chamber 12 are air flues 16, 17, 1S and 19, as shown in Fig. 3, through which air fiues 1G, 17, 18 and 19 fresh air may flow from the air flue 14k to the chamber 12 to be heated therein, but such air flues .1.6, 17, 18 and 19 may be dispensed with, if desired, without destroying the effectiveness of the structure, since the air fiue 13 may be made of suficient size to conduct fresh air into the chamber 12 at a desired rate of flow. Extending through each of the side walls of the brick inclosure 9 at a point near the top thereof is an outlet opening 20 within which is disposed a perforated disk or wire netting, which openings 2O serve to permit heated air to pass from the chamber 12 into the room containing the structure.

Obviously other passageways and conduits may be provided for conducting heated air from the chamber 12 to other roomsthus to heat such other rooms. v

Manifestly a fire burning on the grate 15 will impart great heat to the walls 6 and 7 and to the wall of the air flue 13 while the products of combustion as they pass through the smoke flue 8 will highly heat the walls thereof and all of such walls will rapidly conduct heat to the fresh air within the chamber 12 to heat such fresh air which may then pass out through the openings 20 into the room thus adding its heat to the heat that is directly radiated through the front opening of the fireplace.

Preferably I make the fire receptacle of cast iron with integral walls, but it may be made of iron plates oined together or portions of it may be made of cast irony and other portions made of sheet iron; and

changes may be made in the form, dimensions and arrangement of different parts of my invention without departingV from the spirit thereof.

Vhat I claim is:

In a lireplace of the character described, asubstantially rectangular casing of refractory material having an opening in itsfront wall and provided with a vertically-disposed n rear wall, a flue leading upwardly from the casing, the back wall of the Hue forming a continuation of the back wall of the casing, a lire receptacle held within the casing and comprising a bed plate extending across and closing the bottom of the casing, Vertical walls rising at each side 0f the'bed plate, a curved rear wall extending upward from adjacent the back of the bed plate and closing the space between the vertical side walls, said curved rear wall and bed plate having alined openings, an air line carried by the curved wall and projecting forwardly into the heat and combustion chamber of the fire receptacle, a back diagonal wall extending downward and forward from the back wall fd of the casing to the curved rear wall, and a front diagonal wall extending downward and forward in parallel spaced relation to the back rear wall to form a smoke passage leading to the tube, the bed plate formed with openings and carrying vertical thimbles positioned in the casing over said openings rearwardly of the fire receptacle for the admission of air, the outlets for the thimbles being positioned above the bed plate 1 OTTO F.
